Maximum flow
The maximum flowrate associated with Maximum head (2.13.4.2.) (Page 243).
Index Single-point model Dual-point model
Global Transducer
Values Range: -999 ... 9999
Preset: 1000
This represents the flow at the highest head level supported by the PMD and works in
conjunction with Maximum head (2.13.4.2.) (Page 243) to define the highest point in the
exponential curve. Use it when the PMD requires a maximum head and flow reference point.
This would include Exponential, Palmer-Bowlus Flume, H-Flume, and Universal breakpoints.
Also, use this parameter with Flow time units (2.13.4.4.) (Page 244) to define the flowrate
units. The limitation of four digits is for the LCD only, and the flowrate value is available with
greater precision through communications.
Note
• The display of the measured value is limited to six digits. A Maximum Flow value larger
than seven characters will not display correctly.
•
If measured value is larger than seven characters, the screen displays ####. A larger unit
[Flow time units (2.13.4.4.) (Page 244)] should be used, or number of decimal points
[Flowrate decimal (2.13.4.6.) (Page 245)] should be reduced.
Flowrate decimal
The maximum number of decimal places to be displayed.
Index Single-point model Dual-point model
Global Transducer
Options No digits
1 digit
*2 digits
3 digits
In RUN mode, the number of decimal places displayed is automatically adjusted (if
necessary) to prevent the number of Flowrate digits from exceeding display capabilities.
The maximum number of head decimal places is controlled by Decimal position (2.12.4.)
